To all whom it may concern:

Be it known that we, ALFRED H. SMITH and HARRY WANAMAKER, citizens of the United States, and residing, respectively,

in the city of New York, State of New York, and city of Albany, ,State of New York,

have invented certain new and useful Improvements in Locomotive Ash-Pans, of

which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part ofthis specification, in which- Figure lis a side elevational view ofsan ash pan of our improved construction. Fig.

. 2 is an end elevation of the ash pans Fig.

3 is a vertical section taken approximately on the line 3- -3 of Fig. 1. Fig. & is an enlarged detail sectional view of one of the ash pan door operating mechanisms;

Our inventlonrelates generally to loco- :motive ash pans, and more particularly to certain novel features ofconstruction of the operating mechanism utilized for opening and closing the drop doors which normally close the opening atthe bottom of the pan. The present applicationv isa division of an application filed by us J anuary 14:, 1913, Serial No. 741,995. v

Certain types of ash pans now in general use are in the form of hoppers having drop doors hinged so as to swing downward and outward to permit the discharge of the ashes from the ash pan, and it is the primary object of our invention to equip the doors of thistype of ash pan with a simple and compact operatlng mechanism, which can be manipulated with little power to effect the opening and closing movements of said 1,

suitable manner to these rock shafts are plates 11, the same constituting drop doors for the bottom ofthe pan, one of these plates is slightly wider than the other so that its free edge 14 overlaps the corresponding edge of the opposite door.

J ournaledin suitable bearings 15 at the lower. end of one of the end walls 11 is a transversely disposed rock shaft 16, one end of whlch is extended and provided with a'lever17 by means of which said shaft'may be readily rocked. ,This'lever 17 normally rests on a suitable support 18, and if desired, suitable operating connections may be extended from this lever 17 to the interior of the locomotive cab. Fixed on this rock shaft 16 near the bearings 15 are short upwardly projecting levers 19, and pivotally connected tothe upper'end of each'of these levers is 'a horizontally disposed link 20. These links extend along; the sides of the ash pan and their rear endsare pivotally connected to themeetingends of pairs upper ends of the upper links of each pair are pivotally connected to bearings 22, the

of verticallydisposed toggle links 21. j The same being arranged on fixed portions of the locomotive frame.

the outer ends of the short curvedarms 23 v The lower "ends of f .the 'lowerlmks are pivotallyi connected to in any suitable manner to the adjacent rock shafts l3.- 1 Under normal conditions, or

when the doors .are closed, as shown in Figs.

2 3', the toggle links'21 occupy vertical posltions, and the lever )17 rests upon its support 18. To open the'doors, the free 1 end of the lever 17 isengaged and'raised,

thereby rocking shaft'16 and consequently swinging the .levers19 forward into the position shown by dotted lines in Fig. L

This operation draws the links 20 forward,

thereby actuating the toggle links 21, and J as the upper end ofithe upper one of each pair of links operates in fixed bearings, the lower links will bewdrawn upward as shown by dotted linesin Fig. 1, thereby pulling the outer ends of the-curved arms 23'upward, which movement rockstheshafts 13,

and consequently swings the doors 14 downward, and outward into thepositions shown by dotted "lines in Fig. 3.

During the movements 1' toggle links 21 willjswing outward slightly by reason of;-the change of position of the arms 23, and to permit such outward swinging movement of said links, the upper ends list described, the

of theupper links have a certaln amount of transverse play in the bearings 22, and likewise the lower ends of the lower links are flexibly connected to the outer ends of arms 23. A reverse rocking movement imparted to shaft 16 brings about reverse movement of the parts just described, and as'a result, the doors is are moved into their normal closed positions with the edge M of one door overlapping the adjacent edge of the opposite door as shown in Fig. 3.

An ash pan door operating mechanism of our improved construction is comparatively simple, is very compact, does not interfere with the free working of any of the operating; parts of the locomotive, and by utilizing toggle links and short connections between said links and the doors, said operating mechanism can be manipulated with the expenditure of comparatively little power.

It will be readily understood that minor changes in the size, form and construction of the various parts of our improved locomotive ash pan may be made and substituted for those herein shown and described without departin from the spirit of our invention,- the scope of which'is set forth in the appended claims.

We claim: r

1. The combination with a locomotive ash pan, of shafts journaled on opposite sides of the lower portion of the pan, doors carried by said shafts for closing the opening at the bottom of the pan, crank arms fixed to said shafts, a pair of toggle links arranged between each crank arm and a fixed part of the locomotive frame, the upper ends of the upper links being so connected to the fixed,

part of the frame as to permit said links to swing longitudinally and transversely with respect-to the axis of the pan, the lower ends of the lower links being so connected *tovthe crank arms as to permit said links to swing longitudinally and transversely with respect to the axis of the pan, a rock shaft arranged in suitable bearings adjacent to one end of the ash pan, and connections from said rock shaft to the joints between the toggle links for simultaneously actuating the latter to move the doors.

2. The combination with a locomotive ash pan, of a pair of drop doors hinged to said ash pan for closing the lower end thereof, a pair of toggle links arranged between the central portion of each door and a fixed part of the locomotive frame the upper ends of the upper links and the lower ends of the lower links being so pivotally connected to the doors and the locomotive frame as to permit said links to swing longitudinally and transversely with respect to the axis of the ash pan, and means connected to the joints betweenthe toggle links for simultane ously actuating the same to move. the doors.

3. The combination with a locomotive ash pan, of a pair of drop doors hinged to the lower portion of the pan for closing the opening in the bottom thereof, crank arins connected to the outer central portions of said doors, toggle links pivotally connected .to'said crank arms, and to fixed parts of the locomotive frame the upper ends of the up .per links and the lower ends of'the lower pan, ofvrock shafts arranged at the sides of the pan near its lower end, doors carried by said shaft for closing the opening at the bottom of the pan, crank arms fixed to sald.

rock shaftsnear their central portions, tog :gle links arranged between each crank arm and a fixed part of the locomotive frame the upper' ends ofthe upper links and the lower Iends'of the lower links being so connected to said crank arms and locomotive frame as to permit said links to swing longitudinally and transversely with respect to the axis of the ash pan, and means connected to each 132111 of toggle links for simultaneously actuating the same to move the doors.

5. The combination with a locomotive ash .pan, of a pair of drop doors hinged to said pan for closing the opening at the lower end jthereof,crank arms connected to sald doors near their central outer portions, a pair of toggle links between each crank arm and a fixed part of the locomotive frame, the ends of which, toggle links are flexibly connected to said crank arms and the fixed parts of the locomotive frame whereby said links can swing simultaneously lengthwise and transversely with respect to the axis of the ash pan, and means connected to the joints be tween said toggle links for simultaneously actuating the same to move the doors.

In testimony whereof, we have hereunto afiixed Our signatures in the presence of two subscribing witnesses.
